Hertz Kompressoren HDD 185 2346 125, 250 HP Rotary Screw Air Compressor

The Hertz HDD 250 HP rotary screw air compressor is  designed to reduce power transfer losses with a directly-coupled motor and screw block. The HDD Series features a microprocessor controller, Wye-Delta starter, patented and durable screw block to provide high capacity air, and suction filter with silencer casing. The three stage air and oil separator efficiently separates at lower volume with deeply wrapped, intertwined separation layers, resulting in outlet air oil mist content at 3ppm. The cooling system includes independent radiator segments and a silent, slow speed radial fan controlled by a secondary fan inverter.
